To wHoM Ir MAY eoNoERNz.

Be it known that I, GEORGE NEILSON, of Boston, in the county of' Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in Lamp-Burners; and I hereby declare the following to bea full', clear, and eriactdescription ot' the same, reference being had to the accompanying drawings.

My invention relates to the class of burners in which a deliector, elevated at some distance above the base of the burner, iscombined with an air-supplyY cylinder, u pon which itrests; and its object is, first, to produce a burner of this description, the component parts of which may be separated and ldetached. from each other readily, thus facilitating the cleansing` and-repairing or manipulating of the burner; second, to aii'ord increased security and support for the chimney, and-so prevent it, as far as possible, from being detached or shaken from its seat by any sudden vjar or shock.k

The following are the essential characteristics of the invention, by which I have realized the above results. First, the combination, with the wick-tube and air-supply cylinder, of a deiiector, hinged to said cylinder. Second, the combination, with the ehimney-seat and wick-tube, of an air-supply cylinder, detachable or removable from its seat, and a deliector hinged to the air-supply cylinder. I

Third, the combination, in a burner such as described, j'ot'- a chimney-rest, air-supply cylinder, and deector, when the said parts are capable of being removed from or applied t'o the'burner, bodily and together.

Fourth, the combination, with the base and wick-tube, of a chimney-seat, air-supply cylinder, and deliector, when the said chimney-seat, cylinder, and deiiector are removable or detachable from the base and wick-tube,

and from one another.

Fifth, the combining with and attaching to the air-supply'cylinder,V springs, or equivalent devicesforb` steadying the chimney. A

Sixth, forming a bevelled seat for the chimney, whereby thelatter is rmly held in position.

These, and *otherfeatures of the burner in which my invention consists, will be readily understood by reference to the accompanying drawings, in which- Figure 1 is a side elevation of the burner, i

Figure'Q is a vertical'central section, and

Figure 3 is aplan view of the same.

A represents the deflector, hinged at a to the top of the air-supply cylinder B, whose lower end its around the raised cylindrical portion l of the chimney-rest D, which part Z1 supports or carries the diaphragm or perforated air-distributer e, and the latter fits around the flat-wick tube O, preventing the rotation or displacement of the chimney-rest D, on which the air-supply cylinder and deliector depend for their support. l The chimney-rest D is in turn supportcd on a bell-shaped or Haring frame, E, the lower and contracted or drawn-in end of which is secured to or forms part of the base or lamp-reservoir cap F. The framefE has a number of openings formed init, which, in effect, divide the frame in`to a series of arms or standards, upon the top of which the plate D rests. The deliector isi hinged to the cylinder-by means of a srnall hook or bent arm, a, the endof which is inserted into a slit, UZ, of corresponding size, formed in the side of the cylinder, as shownin ig.'2. Upon the opposite side of the de'llectoris a springfclasp, f, which, when the delieetor is down,'catches upon the cylinder, and

` -thus holds the dcllector iirmlyin place. The construction of the hinge-joint, just described, is such asto admit of the deilcctor being removed, andseparated from the cylinder whenever desired. The cylinder can also be readily slipped on and off the part around which its lower end iits. Its position when fitted on the part lz is determined by a lug, c, which lits in a recess, g, of like shape, in the-cylinder. The latter -is thus5 held in such posi-4 tion that the slot in the hinged dome will be accurately placed with respect'to the wick-tube. The chimneyyrest is likewise capable of being removed from or adjusted to the burner. The diaphragm c, which ts closely around the Hat-wick tube, serves to steady the chimney-rest, and to prevent its lateral displacement, while the frame E supports it and the' parts which it carries.

It will thus be seen that by lifting oli' the chimney-rest, the chimney, cylinder, and deliector will be removed bodily and together, while at the same time these parts can also be detached and taken apart from each other. All parts of the'burner can, therefore, be readily handled and cleaned.

In order to more eiectually hold the chimney in position, that portion of the rest D,Iwhich constitutes the chimney-seat c, is bevelled or inclined, as seen in gs. 1 and 2, ne that when the base of the chimney is presseddown upon this bevelledvor sloping surface, it will become in some measure jammed or wedged thereon, and will thus be held erect and rmly, and prevent the chimney from beingY accidentally tilted or shaken from its seat, A series of springs, or equivalent elastic and yielding devices, l, are attached to andv project from the airsupply cylinder, so as to bear against'theinterior of the chimney, and thus contribute to its support.

By combining in this manner these necessary spring-devices with the cylinder, I am enabled to remove them readily from the burner with the cylinder,`a;nd thus leave the chimney-rest free to be manipulated or cleaned. The course of the air in the burner is indicated'by the arrows in iig. 2. It enters the openings in the frame E, ascends through the air-distributing diaphragm c, and then passes out .with the dame through the slot in the deflector, and through the apertures s formed in the top of the same.

Thebevelled chimney-seat may be formed as shown in the drawingsn'or in any other ordinary or suitable manner. I have contemplated making the lower end of the air-supply cylinder flaring for this purpose, in which case the chimney-rest D may be dispensed with, and the air-distributing diaphragm c attached directly to the bottom of the said cylinder.

Having now described my'inventiou, and the manner in which the same is or may h'e carried into effect, what I claim, and desire to secure by Letters Patent, is

1. The combination, in a burner such as described, of the air-supply cylinder, with a deilector hinged to the said cylinder, substantially as and for the purposes herein shown and set forth. I

2. The combination, -with the chimney-rest and wick-tube, of a'n air-supply cylinder, detachable or remo-vable from its scat, and a deilector hinged to the air-supply cylinder, substantially as and for the purposes herein shown and set forth.

3. The combination, in a burner such as described, of a chimney-rest, air-supply cylinder, and deector,

'when the said parts are capable of being removed lfrom and adjusted to the burner bodily and together, substantiallyas and forthe purposes shown and'specified.

4. The combination, with the base and wick-tube of a lamp-burner, of a chimney-rest, air-supply cylinder, and deector, when the same are detachable from the said base and wick-tube, and from one another, snbstnntially in the manner and for the purposes shown and described;

5. The combination, with the air-supply cylinder, of chimneysupporting springs, attached to and prejectl ing from said cylinder, substantially as herein shown and described.

In testimony whereof, I have signed my name to this speciiication before two subscribing Witnesses.
